bayt-un, "a" house. al-bayt the house... hopefully they will introduce endings and beginnings to words soon. and the 3 is ayn, its sometimes like swallowing the A, there is also a gayn in my opinion is worse. more to swallow lol check alif ba ta on YouTube you'll here each letter pronounced.
What is the actual sound made by the first letter in the second word? It seems to be confusing the TTS a bit, and all through the last lesson where it was introduced, it was represented in English by '3', which of course does not help with pronunciation whatsoever and yes I reported it on every question.
When it's at the front of the word, it sounds almost silent, but when it was in the middle it sounded kind of like a wobbly h. Is this an h sound or a glottal stop or what?
From the tips and notes section of Countries 1 I inferred that 3 is sort of the anglicised texting way of writing this letter, since it looks like a backwards 3 and there is no way to write it phonetically in English. (There should probably still be something in the tips and notes for this lesson explaining that, otherwise it just looks like a typo and will probably bring in a lot of reports.)
As for the pronunciation, it's very hard to describe, so here is a video of someone else doing it:
